Application filed February 7, 1382. (Nomodeh) To all whom it may concern: I

' Be it known that 1, WILLIAM J. MORTON, a resident of the city, county, and State of New York, have invented certain new and useful improvements in Fluid-Motors; and I do hereby declare that the following-is a full, clear, and exactdescription thereof, refiereuce being had to the accompanying drawings,and to the letters of reference tnarked thereon, making apart of this specification.

This invention relates to'that class of prime movers in which a Wheel bearing upon and compressing an elastic tube is propelled by the distention of the tube under and behind the wheel.

The objects ofmy invention are, first,.to secure the advantage of a high velocity in the fluid column employed to distend the tube and a diminution of loss from its friction in passing, through the tube byimparting totheengine constant, rapid succession of distinct impulses from a short pressure-tube, instead of longer-continued pressure from an extended tube; second, to secure a pronfpt, rapid dis charge or exhaust of the motive tluid trom the elastic propelling-tube so soon as it has performed its work; third, to secure, in combine tion with a plenum in the supply-pipe on the one side,the advantage of an cxhaustof pressare in the discharge-pipe on the opposite side to increase the power of the engineg'fourth, to produceau effective combination of the supply and of the discharge pipes within the frame or casing of the engine, rendering it'neater and more compact. I attain these ohjects by means oi the devices hereinafter fully dcscrihed.

in the accompanying ilrawings Figme 1 is a perspective view, partly in section, of my improved motor adapted to rotate in a horizcntl plane within an annular tubular casing,

through which the water is conducted to the eiastic' tubes, the motor being represented as titterlupon and e'ihausting into a wash-basin. Fig. 2 is a side elevation, and Fig. 3 an end View, partly in section, of the motor adapted to rotate in a vertical plane within a double annular casing to which the elastic tubes are connected, both for their supply and exhaust, and with an increased numberof motor-wheels Fig. 4 is a side elevation,

and Fig. 5 a central transverse section, of the motor in a simple form without casing and with but h single elastic tube.- Fig. 6 is acentral lon gitndinal section, Fig. 7 aceutral transverse section,and Fig. 8 a top view, of a modiflcation of the motor constructed to rotate in avertical plane over two elastic propellingtube's adapted toavoid a dead-center. Fig. 9 is a transverse sectional view of a motor-wheel and bearing-block detached, illustrating an improved shape of both wheel and block. Fig. 10 is an end view or front elevation, and Fig. 11 a. transverse section in line 00 a: of Fig. 10, illustrating the motor when constructed with 'adouble set of motor-wheels on the same shaft, and illustrating, also, the extension of thetlischarge-pipe to produce a siphonal action. Fig. 12 illustrates the motor constructed with three large motor-wheels, as in Fig. 1', but adapted to rotate in a vertical plane with separate supply-pipes for each propelling-tube, and siphonal exhaust-pipes.

' A A are the propelling or motor wheels, and B the central shaft or spindle, of myimproved motor. The wheels all rotate freely at equal distances from the central shaft, each preferably upon an axis parallel thereto, which is supported by radial arms or flanges G 0 projecting therefrom, although in a modification of my invention illustrated in Fig. 13 the propelling-wheels rotate upon axes which are radial to the shalt I The shaft maybe made to rotate equally well in a horizontal plane, as shown in Fig. 1, or in a vertical plane, as shown in Fig, 2.

D D are short segmental blocks, each having an inner face conforming to the arc of a circle having the axis of the shaft as its center, and which are placed in the line of travel of the propelling or motor wheels A A, so that the latter may revolve in close proximity thereto. The interval hetweenveach bearing-block and the motor-wheels passing over it is adjusted by devices designed to produces movement of the block to and from the shaft-such as set-screws cl (1, Figs. 2 and 12, or sliding wedges e e, as shown in Fig. 6, or otherwise by an ad justm-cnt ot the hearings of the central shaft itself through the interposition ofa set-screw, L, as shown in Figs. 4. and 5.

Shortelastic tubes F are led over each of TOG the segmental bearing-blocks I), so as to be compressed by the motor-wheels A A as they revolve over it, each tube being connected with a supply-pipe, G. h

The outer end of each tube may be left open for a free discharge, as shown in Fig. 1, or be connected with a suitable dischargemipe, S, which may be very advantageously extended, as shown in Figs. 11 and 12, so as to produce a siphonal or exhaustive action upon the contents of the elastic tube F in the operation of the machine. a g

The supply-pipe or both the supply and discharge pipes may be arranged in the form of an annular casing to encircle the motor, the elastic tubes F being readily connected to the one pipe and the other by means of suitable nipples formed or fitted thereon, as shown in Figs. 1 and 2.

The blocks D are so proportioned in length as that one wheel shall pass upon the tube as the other leaves it. The elastic tubes F F may be protected against wear or undue strain by inclosing each in an outer tube or sleeve of suitable textile material, inelastic, yet soft and flexible, and so proportioned in diameter as to permit the necessary expansion or dilation of the inclosed tube under pressure, and yet pre-. vent its undue expansion and aflord it proper support.

Projecting edges or flaps may be left upon the outer sleeves to facilitate their attachment to the bearing-blocks.

The outerperiph'ery'or rim of each motorwlieel A is by preference made slightly convex in cross-section, and the center of each bearing-block D is-likewise made somewhat convex in cross-section, as illustrated in Fig.

' S), so that in the compression of the interposed elastic tubes F the folded edges of 'the tubes shall be relieved from undue compression, the greatest pressure being brought to bear upon the center thereof. (See Fig. 9.)

The motor may be constructed with a large number of motor-wheels A A,.revolving over a single hearing-block D and elastic tube F, as shown in Figs. 4 and 5, and the adjustment of the wheels to the bearing-block be made by fitting the bearings of the central shaft,.IB, in

a hanger, K, (see Fig. 5,) to be suspended by one or more set-screws, L, from a frame, M M,

over the bearing-block: To avoid the deadpoint possible in the operation of a motor constructed as last above described, two bearingbloeks D 1) may be used, supporting two elastic propelling-tubes F F, which may each be connected with a single supply-pipe G and a single discharge-pipe, H, as shown in Figs. 6 and 8. In this case one of the series of motorwheels on the central shaft, B, will always-be" under pressure, so that no dead-point can occur in its movement. The drawings, Fig. 6, illustrate, also, the use of sliding wedges actuated by set-screws for the purpose of adjusting the bearing-blocks D D, the. bearings for the shaft being fixed in the frame M M.

In the form of the motor illustrated by Figs. 10 and 11 a double set of motor-wheels are supported around the central shaft between three parallel radial flanges, N N N, thewheels between the central flange and the outer flange on one side alternating in their position with the wheels; between the central and outer flanges on the other side, as shown in Fig. 10 and dotted lines, Fig. 11. In such case two elastic tubes F are em ploycd--onc for each set of wheels-and are laid side by side upon a single bearing-block D, which is adjusted by means of an eccentric shaft or roller, P, interposed betwcen the bearing-blocks and bedplate of the frame, as clearly shown in Fig. 11.

When the frame supporting the shaft, motorwheels, bearing-blocks, and elastic tubes of the engineis constructed in the form of an annular, tubular, or hollow casin g, it may em brace either a single conduit for the snppl y of water to the elastic propelling-tubes, as shown in Fig. 1, or double conduits, as shown in Figs. 2 and 3, through which both the supply to and the discharge of the water from the elastic tubes may be efiected.

It the annular tubular casing be made single,.it may be titted-with lugs V V to engage the rim of a wash-basin or receiving-vessel, Y,

' and thus support the motor thereon in a horizontal position, as shown in Fig.1. In this case the elastic propelling-tubes are connected to nipples on the inner side of the rim, and after being led thence over the bearing-blocks are left free to discharge into the basinor vessel beneath. An outside nipple adapted to receive a flexible pipe. G, facilitates the connection of the motor with a cook or faucet for its water-supply, as shown in Fig. 1. When the annular casing is made double, as shown in Figs. 2 and 3, one division thereof is coupled with a supply-pipe, G, and the second division with a discharge-pipe, S, the elastic propellingtubes being each attached at one end to a suitable nipple upon the annular supply-conduit W, and after passing over the hearing-blocks is connected to the annular discharge-conduit W at the other, as shown in Figs. 2 and 3.

In the operation of my improved motor the fluid, upon entering the short elastic tube f, which has been compressed by the bearing of one of the motor-wheels A thereon, will,b v

causing a distention of the tube against tho' periphery of the wheel, force it forward, and as the continued supply produces a continuation 'of the distention following closely after the moving wheel,a constant pressure is thereby maintained against said wheel to drive it forward until it has passed off from the bearing-block upon which the tube is supported,,

whereupon the latter will exhaust itself into the discharge-pipe and be'thus relieved. The pressure from the supply is meantime cut oil by the approach of the next wheel in the series, which will thereupon, under the influence of said pressure, he in turn driven forward in the same direction.

By a multiplication of small motor-wheels, in combination with one or two short bearingblocks and interposed elastic tubes, 2. quick succession of powerful impulses is imparted to the central shaft under thefull pressure of the head in the supply-pipe without appreciable loss from friction, and a high velocity may be readily attained therein. Each wheel receives in turn an impulse due to the full force of the pressure in'the supply-pipe exerted upon the periphery of the wheel by the distention of the tube against it. This pressure is increased by making the discharge-pipe air-tight and so lengthening it as that the discharge of water through it shall exhaust the airtherefrom,thus calling into playatmosp'heric pressure upon the column of water bearin g against the wheel.

This improved motor is especially adapted for driving sewin g-machines,small lathes, dental engines, and other light work. It may be readily adapted to operate a pneumatic dental hammer, or pneumatic perforating-pen formaking autographic stencil-plates, &c., by se- Ullllllfl an'elastic bulb or air-ball, P, in position (see Fig. 4) to be struck by the periphery of each of the motor-wheels A Ain the rotation of the shaft 15, so that each contact shall serve to produce a pulsation'in the column of air con-- fined in the transmitting-tube connected therewith, and I contemplate making this feature of my invention the subject-matter of a separate application for Letters Patent.

The apparatus constructed as described may he used as a pump by connecting either the supply or the discharge pipe with a reservoir of water and rotating the. shaft and motor wheels toward the same. A suction will be thereby produced in the pipe suificient to cause an ascent of water therein -to a moderate height, and the water so introduced will be forced onward and outward through the-flexible tube to a'height proportionate to the power exerted in rotating the shalt.

I donot deem it necessary to enumerate .the many advantages .of my simple motor constructed as described.

I claim therein asnew'and desire to secure by- Letters Patent- 1. The combination, with a series of motor- V wheels revolving about and carried by a; central shaft, of one or more segmental bearingin a radial direction, and of one or more interposed elastic tubes adapted to be compressed by the wheels against said bearing-blocks, and which are each connected at one end with a supply-pipe and arranged to discharge freely purpose herein set forth.
